Answer:
See below
Step-by-step explanation:
1)
Once
[tex]-3\sqrt{8} = -6\sqrt{2}[/tex], it is an irrational number because [tex]\sqrt{2}[/tex] is irrational.
[tex]2\sqrt{3}-\sqrt{27} = 2\sqrt{3}-3\sqrt{3}=-\sqrt{3}[/tex], it is an irrational number because [tex]\sqrt{3}[/tex] is irrational
2) In order to compare those two fractions put them in the same denominator.
Once
[tex]\dfrac{4}{13} = \dfrac{40}{130}[/tex]
[tex]\dfrac{3}{10} = \dfrac{39}{130}[/tex]
So,
[tex]\dfrac{39}{13} > \dfrac{40}{130}[/tex]
This is because, when two fractions have the same denominator, the larger number between them is the fraction with the lowest numerator.
Both are rational numbers because both denominator and numerator are integers.

Answer:
3x5 are factors of 75
Step-by-step explanation:
good day mate
Answer:So, the prime factors of 75 are written as 3 × 5 × 5 or 3 x 5^2, where 3 and 5 are the prime numbers.
Step-by-step explanation:Step 1: Start by dividing the number by the first prime number 2 and continue dividing by 2 until you get a decimal or remainder. Then divide by 3, 5, 7, etc. until the only numbers left are prime numbers. Step 2: Write the number as a product of prime numbers.

The function f is continuous on the interval (0,9) and is twice differentiable except at x = 6, where the derivatives do not exist (DNE). Information about the first and second derivatives of f for some values of x in the interval (0,9) is given in the table above. Which of the following statements could be false?
Answer:
The statement that could be false is;
(C) The function has a relative minimum at x = 6
Step-by-step explanation:
The given parameters are;
The function is continuous in the interval 0 ≤ x ≤ 9
The function is not differentiable at x = 6
f prime (x) = Negative for 4 < x < 6, and positive for 6 < x < 8
Therefore, at x = 6, the function is vertical
The statement that could be false is that the function has a relative minimum at x = 6.
A continuous function f(x) does not have discontinuity at any point
The statement that could be false is (c). The function f has a relative minimum at x = 6.
The interval is given as:
Interval = (0,9)
From the question, we understand that the function is not differentiable at x = 6.
This means that the function may or may not have a relative minimum at x = 6.
Hence, the statement that could be false is (c).

The Perimeter of a Rectangle
Given a rectangle of dimensions W and L, the perimeter of the rectangle is:
P = 2W + 2L
Or, equivalently:
P = 2(W + L)
The dimensions of the icon for the mobile app are 1.5 cm and 3 cm, thus:
P = 2(1.5 cm + 3 cm)
P = 2(4.5 cm)
P = 9 cm

Lily plans to paint a stencil design on the wall in her room the stencils has one part yellow 3 Part Blue and 4 parts are blue and 4 parts are white .The area of the the walls that she must paint is 480 square feet a quart of paint approximately covers 80 square feet .what is the minimum amount of paint that Lily needs to buy
Answer and explanation:
Since a quarter(1/4) of paint covers 80 square feet, a whole paint would cover 80×4= 320 square feet of the wall
Remaining part of the wall left unpainted after using one whole paint
480-320= 160 square feet
Therefore paint required for remaining unpainted part
= 160/80= 2 quarters of paint(1/4+1/4)= 1/2 paint
Total paint required for the wall = one whole paint + half paint = 1+1/2= 1 1/2
Total paint required is one and half
Or
We divide area of wall by area of wall covered by each quarter
480/80=6 quarters of paint
6 quarters of paint = 1/4+1/4+1/4+1/4+1/4+1/4
We still get same answer
= 1 1/2
Answer: A 1 quart yellow, 2 quarts blue, 3 quarts white
Step-by-step explanation:
if u divide 480 by 80 you will get 6 so u will only need 6 quarts of paint.

Is this sentence Law of Detachment, Law of syllogism, or invalid
Answer:
The law of detachment and syllogism is valid here
Explanation:
The law of detachment and syllogism is associated with inductive reasoning. This law states that a conclusion is valid if the premise or hypothesis is valid, therefore if a then b. In others a results in b.
The law of detachment is denoted
[(a→b)∧a]→b
The law of syllogism derives from the law of detachment. Syllogism says that if a results in b and b results in c, then a results in c. In other words since a causes b and b causes c, then if a then c.
It is denoted
[(a→b)∧(b→c)]→(a→c)
In the above example, given: If you live in Orlando, then you live in Florida
Morgan does not live in Orlando, therefore it is concluded that he does not live in Florida

A 0.7 kg toy car accelerates at 0.5 m/s2. The FORCE is...
0.35 m/s2
0.35 kg
0.35 N
Answer:
[tex]\boxed {\boxed {\sf 0.35 \ N}}[/tex]
Step-by-step explanation:
Force can be found by multiplying the mass by the acceleration.
[tex]F=m*a[/tex]
The mass of the toy car is 0.7 kilograms and the acceleration is 0.5 m/s²
[tex]m= 0.7 \ kg \\a= 0.5 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F=0.7 \ kg * 0.5 \ m/s^2[/tex]
Multiply.
[tex]F=0.35 \ kg*m/s^2[/tex]
1 kg*m/s² is equal to 1 Newton. The units for force are Newtons.Therefore, our answer of 0.35 kg*m/s² is also equal to 0.35 Newtons[tex]F= 0.35 \ N[/tex]
The force of the toy car is 0.35 Newtons
Answer:
(45 kg)(4.1 m/s)2 = 120 N

To find the y intercept set x=0
You are given two points: (7,-6)(-4,27)
y=mx+b
y2-y1=x2-x1
x1=7
y1=-6
x2=-4
y2=27
27-(-6)/-4-7=27+6/-4-7=33/-11=-3
y=-3x+b
-6=-3(7)+b
-6=-21+b
+21 +21
b=15 so, y=-3x+15
PLUG IN O TO THAT EQUATION
y=-3(0)+15
Your y intercept would be 15
